What is the difference between steel wheels and alloy wheels?

[LaTalia]

The differences between steel wheels and alloy wheels are as follows: 1. Alloy wheels: Alloy wheels actually contain other metals, such as iron, so they should be called aluminum alloy wheels. 2. Ordinary steel wheels: Compared to ordinary alloy wheels, steel wheels have better toughness but poorer hardness. 3. Pros and cons of alloy wheels: Alloy wheels are the opposite, with better hardness but poorer toughness. However, their main advantage is lower production costs through stamping, which is why they are often equipped on basic car models. Additional information: Drivers may notice that after enduring potholes on the road, steel wheels show no significant changes but start to vibrate at speeds close to 100 km/hr. This is because they are stamped, resulting in imprecise contours and mass distribution, inevitably causing unbalanced rotational inertia and vibration. Alloy wheels generally do not exhibit high-speed vibration. To enhance the cooling of the braking system, they are designed with numerous cooling holes, which, however, reduce the strength of the wheels, making them more susceptible to deformation upon impact.
